NCT03163758

Brief Summary

The study aimed to figure out brain structural and functional reorganization evidence after repetitive transcranial magnetic stimulation through the method of neuroimaging brain network analysis, such as resting-state functional magnetic resonance imaging and diffusion tensor imaging.

Outcome Measures

Primary Outcomes (3)

  • National Institutes of Health Stroke Scale (NIHSS)

    The investigators use National Institutes of Health Stroke Scale (NIHSS) to evaluate the participants' neural deficit after stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. Higher NIHSS scores mean a worse outcome.

  • Barthel Index (BI)

    The investigators use Barthel Index (BI) to evaluate the participants' activities of daily living after stroke. The BI consists of 10 questions that relate to degree of independence with activities of daily living, including toileting, bathing, eating, dressing, continence, transfers, and ambulation. The BI score is calculated by summing the response value to each of the 10 questions. The BI score ranges from 0 to 100. A patient scoring 0 points would be dependent in all assessed activities of daily living, whereas a score of 100 would reflect independence in these activities. A higher score is associated with a better outcome.

  • Fugl-Meyer Assessment Upper Limb (FMA-UL)

    The investigators use Fugl-Meyer assessment Upper Limb (FMA-UL) to evaluate the participants' motor function of upper limb. The FMA-UL is an ordinal scale that has 3 points for each item. A zero score is given for the item if the subject cannot do the task. A score of 1 is given when the task is performed partially and a score of 2 is given when the task is performed fully. The maximum score of FMA-UL is 66 and the minimum score is 0. Higher scores mean a better outcome.

Study Arms (2)

rTMS treatment group

EXPERIMENTAL

The rTMS treatment group received a 10-day real repetitive transcranial magnetic stimulation (rTMS) treatment beginning within 1 week after stroke onset.

Device: real Repetitive Transcranial Magnetic Stimulation

sham group

SHAM COMPARATOR

The sham group received a 10-day sham repetitive transcranial magnetic stimulation (rTMS) treatment beginning within 1 week after stroke onset.

Device: sham Repetitive Transcranial Magnetic Stimulation

Interventions

The rTMS treatments were performed using a Medtronic MagPro type magnetic stimulation device (Medtronic, Minneapolis, MN, USA) and a figure-of-eight coil (MC-B70, Medtronic). Coils were placed tangent to the scalp. The stimulation protocol involved 50 trains of 20 pulses applied over the ipsilesional M1 at a frequency of 5 HZ, with the stimulus intensity set at 120% of the resting motor threshold of the unaffected extremity.

rTMS treatment group

The sham rTMS was performed on the same site as the rTMS treatment group but without any true stimulations. Coils were placed perpendicular to the scalp.
